The placement can be affected by
1) Subject combination
2) The academic ability of the class
I suggest you to have a talk with the principle or form teacher
about this issue. The reason that you've given seems strong enough
for you to remain in the previous class, but do you results prove
that you are suitable in 4E? Subject combination wise, do you
generally have the same subject combination as your peers?
The reason why the school might place you in a 5N class because
your academic results. 5N go by a slower pace and is in the final
lap of the O level. So the pace will make you absorb better...
